CHARLES L. BOTTUM, OF DANSVILLE, NEW YORK.

IMPROVEMENT IN CHURNS.

Toall whom it may concern:

Beit known that I, CHARLES L. Bor'rUM, of Dansville, in the county ofLivingston, in the State of New York, have invented a new and ImprovedUhuru; and I hereby declare the following to be a full and exactdescription of the same, reference being had to the accompanyingdrawings, similar letters of reference indicating like parts in all thedrawlugs.

Figure 1 is a sectional elevation of my im proved churn. Figs. 2, 3, andtare intended to represent modifications of my im proved churndasher.

The nature of my improvement or invention consists in providinga churnwith a dasher of such form and construction ithat its use will shortenthe process of churning and more thoroughly separate the butter from themilk or cream and collect it, thereby increasing the quantity andimproving its quality, together with devices for regulating the movementof the dasher, as will be more fully hereinafter set forth.

ATo enable others skilled in the art to make and use my invention, Iwill proceed to describe its construction and operation.

A, Fig. l, represents the body of the churn.,

and may be of any suitable shape and materia D is the standardor`fulcrum,provided with two or more holes, for securing the end of thelever O, thus regulating the motion of the dasher B, which is attachedto the lever() at a by the rod f. The standard or fulcrum D should befirmly secured to the churn at E and F. l.For power-churns, the platformB should be extended and the standard or fulcrum D braced, as seen inthe dot-ted lines I and K in Fig. l.

The dasher B, as seen in Fig. i, is of an anguiar form, and may be madeat any desirable angle, (but fixed or permanent so far as its action isconcerned,) possessing two or more sides and composed of one or morepieces of any suitable material, with cross pieces or braces, as seen inthe dotted lines e e, Fig. l.

The dasher B is secured to the rod f at g by .any suitable device, andits sides are provided with perforations or openings at various angleswith their surfaces and of any desirable shape, as may be seen in Figs.1, 2, 3, and 4. The size of the dasher should be such as to fit looselythe cavity of the churn, and onehalfinch play on all sides of the dasheris not considered too much.

Figs. 2, 3, and 4 represent modifications of the dasher B, Fig. i beingthe frstum of' a cone to be used in a round churn. The other modicationsare useful accordingly as the milk or cream is increased or diminishedin thickness or quantity.

Operation: The dasher B is attached to and operated on by the\lever G ata, and the stroke of the dasher should be regulated to the quantity ofmilk or cream by securing the rodf to the lever C, or the lever C to thestandard or fulcrum D, by the holes c c c c c, ascan be seen in Fig. 1.In the actof churning, the dasher should be raised to the sur# face ofthe cream, so that in its downward motion the milk or cream may beforced up the sides of the churn, and, coming over the lupper surfacesor sides of the dasher, become freely and intimately mixed with the aircontained within4 the dasher, and that is forced through the openings ofthe dasher by reason of its pressure on the surface of the milk orcream, thus aerating the'entire mass, equalizing the temperature, andsecuring a uniform and simultaneous separation of the butter from themilk or cream, thereby enhancing the quantity and its quality, for inchurns where theI agitation, temperature, and aeration of the milk orcream are not uniform the -butter will be found in all stages ofcoming,77 as it is termed, in consequence of which a portion is churnedtoo much, which injures its keeping qualities, while thatrichoily'substance that imparts color and flavor to the butter is worked offand incorporated with the buttermilk.

In gathering the butter, the upward motion of the dasher-drawing orsucking-and its downward motion-forcing the minute globules of butter tothe center of the churn and dasher-secure its ready cohesion, and itbecomes solid atonce.

AWhat I claim, and desire tor secure by Letits modifications, incombination with the rod ters Patent, isf, the adjustable standard orfulcrum D, the

1. The use of the angular dasher B, as seen lever C, and the churn A,substantially as dein Fig. 1, and its vaxji'ousv modifications, asscribed. shown in Figs. 2`and 3, with or Without the adjustable rod f,substantially as set forth, Witnesses: and for the purpose described. D.ROWLAND,

2. Thev use of the angular dasher B, with J. C. HoWELLs.

CHARLES L. BOTTUM.
